A loadtest run against a webserver using HTTPS and a self signed certificate will fail to capture any of the traffic. Recording of the load test works fine. After running the test there are 0 entries in Page Specific Metrics and the log is filled with things like this:

[07/25 12:48:24,Telerik.TestStudio.Load.Agent.exe(392:13),Error] ExecutionContext.RunInternal() : WebException detected with no response, Status: TrustFailure for Uri: https://iq-load.com/.
